It can happen in jury deliberations and local groups, in Dáil committees, and in company boardrooms. Too much testosterone can thwart good decision-making. People have long blamed the male hormone for the damaging group dynamic, and now University College London researchers have proven this to be true. Toss in some excess testosterone and cooperation tends to go out the window. Dr. Mark Wright and colleagues at the Wellcome Trust Centre for Neuroimaging at UCL tested the impact of testosterone on the levels of co-operative decision-making accomplished by groups. They publish their findings this morning in the journal Proceedings of the … Read more »

Testosterone can skew one's judgment, creating the impression that decisions are best taken alone even in situations that call for collaboration, according to a study released Wednesday. In a smart set of experiments, scientists led by Nicholas Wright at the University of London showed that women given a dose of testosterone become less inclined to act in concert even when it was apparently in their interest to do so. Finding the right balance between working together and going solo, and knowing when to do one or the other, is an essential life skill. In some circumstances, joining forces with others … Read more »

Unless you've been living in a cave, or under a rock, you've undoubtedly heard the term "Low-T" or seen an advertisement talking about how testosterone declines as men age and how the solution is undergoing testosterone replacement therapy (TRT). It promises an incredible allure: increased libido more muscle mass and strength, exploding energy levels to what they were in your youth, and a host of others. But is that the entire story? Does it come with health risks? Each birthday after 30 means a drop in testosterone levels by approximately 1%, and therefore 10% each decade. Do the math. By … Read more »

Several weeks ago my column, Do you want better sex? struck a resounding note not only with female readers but also with many husbands who want their wives to have fewer headaches. The general response was, Please write more about testosterone and how it can increase female libido. Testosterone, the male hormone, has been called the hormone of desire. In males, the Big T builds muscle for boys and ultimately turns boys into sexually well-functioning men. Women also produce testosterone during puberty, but only about one-tenth as much as males. Later in life, they produce less, and this is why … Read more »

MONTREAL Boys will be boys, as the adage goes, with their boisterous rough-and-tumble play so stereotypically male. Is it the doings of a primary sex hormone called testosterone, long associated with social dominance, masculinity, and strength? Many scientists have explored the role of hormones and conduct, whether in school playgrounds, sports, war, or bedrooms. Now a Universite de Montreal study of five-month-old twins is among the first to tease out the contribution of genetic and environmental factors to circulating levels of this chemical. The research with infant twins suggests that the environment plays a more significant role than genes when … Read more »

A new study suggests that men with more testosterone tend to lie less than those with low testosterone. Researchers in Germany found that those who were given testosterone before the study told fewer lies than those who did not receive the shot. An earlier study has already linked testosterone with risky financial behavior. "Testosterone has always been said to promote aggressive and risky behavior and posturing," said Bernard Weber, a neuroscientist from the Center for Economics and Neuroscience in Bonn, according to the Irish Independent. The study gave 46 participants extra testosterone while 45 others were given a placebo. They … Read more »

A sharp uptake of testosterone products by Australian men has been blamed on ‘disease mongering' by pharmaceutical companies. Testosterone product use jumped 115 percent from about 29,000 products dispensed in 2005 to 62,000 in 2010 following the marketing of a new gel, according to Pharmaceutical Benefits Scheme statistics. Pharmaceutical companies marketing testosterone products in both Australia and Canada found ways to skirt advertising laws by warning that symptoms including low energy, low sex drive, and even falling asleep after dinner could be due to low testosterone levels, researchers said. Advertisements by two companies that ran in Australia and Canada in … Read more »

     Testosterone. For males, this is the magic hormone. As a young boy enters puberty, testosterone begins to flood his system. By his mid-teens, it is becoming a floodgate and keeps flowing throughout his twenties. Why is testosterone so important? Because it makes men MEN. From burning fat to building muscle, from having youthful energy to boosting your brainpower, from having the unbreakable willpower to exuding confidence, testosterone is the key. Most men don't pay too much attention to testosterone when they are young. After all, why should they? It is so easy to take it for granted since … Read more »

Hormone-replacement therapy significantly improved symptoms of metabolic syndrome associated with testosterone deficiency in men, a new study from Germany finds. The results will be presented Monday at The Endocrine Society's 94th Annual Meeting in Houston. Metabolic syndrome comprises a cluster of complications that can increase the risk of heart and blood vessel disease as well as type 2 diabetes. These complications include excess body weight, especially around the waist and torso, and abnormal concentrations of fat in the blood, known as lipids. In particular, patients with metabolic syndrome have high blood levels of the so-called bad fats, or triglycerides and … Read more »

It may be hard to believe but science says that men’s hormones can be effected on a monthly basis by the lunar (or moon) cycle. Especially with the full moon, men suffer from disrupted sleep and increased stress. The hormones affected are the sex hormone, testosterone, and the stress hormone, cortisol, both of which flow regularly through a man’s bloodstream. Lunar Cycle Affects Testosterone and Blood Chemistry in Men The scientists involved in this fascinating study are from research centers in Tunisia and Qatar. In addition to the moon affecting testosterone and cortisol, the scientists also suspect that solar radiation, … Read more »
